Prevalence of pediculosis capitis in children from a rural school in Yucatan, Mexico

We conducted an analytical cross-sectional survey to estimate the prevalence of and factors associated with active head lice infestation. In total 140 children, aged 6 to 16-years, from a public school in rural Yucatan, Mexico, were examined by wet-combing. A structured questionnaire was used to collect information on individuals and the conditions in the surrounding environment. Head lice infestation was found in 19 out of the 140 children tested (13.6%) and this was associated with both lower income (OR 9.9, 95% CI 2.15-45.79, p = 0.003) and a higher frequency of hair washing (OR 8, 95% CI 1.58-50, p = 0.012). Intersectoral control programs that take into account the socioeconomic differences of children should be implemented.

Does it pay to be social responsible? Portuguese SMEs feedback

The research on corporate social responsibility has been focused mainly on Anglo-Saxon countries and big companies. Most scholars agree there is a positive relationship between companies social and economic performance, however, this is not unanimous. Moreover,during economic downturns, companies struggle for survival and might consider corporate social responsibility efforts should be postponed. This research investigates if there is a positive relationship between social performance and key business results using a large sample of small and medium Portuguese companies over an extended period of time. The research results support the existence of valid positive relationships between companies’ social performance and key business results, confirming it does pay to invest in corporate social responsibility even in less favorable economic scenarios and for small and medium companies across all business sectors.

Influência do treino do passo rápido voluntário nas estratégias de feedforward e feedback em Adultos mais Velhos

Introdução:O envelhecimento influencia negativamente o controlo postural, diminuindo a capacidade de recuperar o equilíbrio após uma perturbação externa e consequentemente aumento do risco de queda nos adultos mais velhos Objetivo(s):Verificar a influência do treino do passo rápido voluntário nas estratégias de feedforward e feedback em adultos mais velhos aquando o stepping anterior e posterior, bem como o timing e sequência de ativação muscular, ajustes posturais antecipatórios (APA) e compensatórios (APC1,APC2), comprimento, latência, velocidade média (VM) do passo e estratégias de passo lateral Métodos:19 participantes foram distribuídos aleatoriamente por dois grupos, o grupo experimental (n=9) e o grupo controlo (n=10), estudo randomizado controlado. Ambos foram submetidos a um protocolo de exercício físico durante 3 meses, 2 vezes/semana. Adicionalmente o grupo experimental (GE) realizou o treino do passo rápido voluntário bilateral nas várias direções. A resposta a um desequilíbrio postural em vários sentidos e consequente resposta de stepping anterior, posterior ou lateral foram avaliadas por meio de eletromiografia de superfície e por um sistema de imagem 3D Resultados: Na variação entre o momento inicial e final (M0-M1), durante o stepping anterior o GE, comparativamente ao GC, aumentou e diminuiu significativamente o timing do RF ipsilateral e GemM, respetivamente. Na variação do timing dos músculos BF ipsilateral e contralateral e TA contralateral, o GE diminuiu significativamente menos do que o GC. O GE aumentou significativamente o comprimento do stepping posterior do que o GC. Quanto à variação da latência observou-se que o GE aumentou significativamente do que o GC nos dois steppings. Na variação da VM, do stepping anterior, o GE diminuiu significativamente mais do que GC. O GE aumentou e diminuiu significativamente os APAS e os APC1 do que o GC no stepping posterior e anterior, respetivamente. Verificou-se que a estratégia mais frequente nos dois momentos e grupos foi a estratégia de stepping lateral direto Conclusão: A contínua prática do stepping rápido voluntário parece promover um melhor controlo postural sendo um importante exercício específico para prevenção de quedas

Viva@Matemática project: a different way to see math

Viva@Mat is a project developed by four Math teachers from the School of Industrial Studies and Management (ESEIG) that was born with the fundamental objective of engaging ESEIG students with different math backgrounds in Math challenging activities. Some of these activities were transformed into real palpable materials and others into small interactive ones, being the great majority of them proposed by ESEIG’ students themselves. This small project rapidly grew into something we didn’t expect – it did flow over the walls of our institution to the general involving community – specifically to pre-university schools through the Viva@Math Exhibits – Orange, Blue and Green (the fourth, the Purple one is still in development). Nowadays, Viva@Math Exhibits – the public face of the Project – are itinerant and have been travelling between several, and different institutions (pre-university schools, preparatory schools, libraries, among others), around ESEIG and IPP area of influence and having registered visitors/participants of all ages. In this article we will describe the Viva@Math Project, its different activities that are categorized in some “great groups” like Numerical Trivia, Logic Activities and Mental Calculation, Puzzles, Geometric Curiosities, Magic Tricks, among others, designed to challenge students to use the underlying logical-mathematical reasoning to any ordinary and everyday activity. We will give specific and concrete examples of some of the activities developed and, also, reproduce of the general stimulating feedback the Project receives from the enrolled “actors” (teachers, students and their relatives, institutions, among others). We feel that this Project has become a small “bridge” between the pre-university schools and Higher Education Institutions (HEI), in trying to shorten the “gap” between the institutions of different levels of education and bring them to work together.

A família, uma estratégia para o sucesso escolar. Um estudo de caso com alunos do 2.º ano do 1.º CEB

O estudo que aqui apresentamos tem como objetivos estudar: o impacto do acompanhamento dos pais ou Encarregados de Educação no Estudo Autónomo e na realização dos Trabalhos de Casa, nos resultados escolares e na motivação para a escola e aprendizagens; ainda as necessidades sentidas pelos pais ou Encarregados de Educação ao fazerem este acompanhamento Neste estudo elaboramos seis propostas que planificamos, analisamos e, do seu desenvolvimento, tiramos as respetivas conclusões. As propostas foram dinamizadas pelo professor de turma e investigador em pequenas sessões/reuniões de esclarecimento com os pais ou Encarregados de Educação sendo quatro delas aplicadas num 2.º ano de escolaridade e as outras duas a um 3.º ano. Nas propostas do 2.º ano foram trabalhadas as frações e as estratégias de cálculo mental bem como foi dinamizado o projeto “Clube de Pais Leitores” e o “Concurso de Espantalhos” também aberto à comunidade educativa. Nas propostas do 3.º ano de escolaridade abordamos as propriedades da multiplicação, sua utilização no cálculo mental, a consolidação da operação divisão através do jogo do 24 e orientações para o Estudo Acompanhado e Trabalhos de Casa para auxiliar os pais ou Encarregados de Educação. Com a implementação destas tarefas, apresentamos os tipos de envolvimento parental solicitado por cada atividade, os benefícios para a família, aluno e professor, os sistemas envolvidos no processo de desenvolvimento da criança e os fatores que influenciaram negativamente na realização destas atividades. A implementação destas atividades foi feita seguindo uma metodologia qualitativa, inserida num contexto de um estudo de caso. Os participantes no estudo foram entrevistados com o objetivo de completar o estudo realizado através do seu feedback. Neste estudo fizemos uma revisão bibliográfica e abordámos o envolvimento dos pais ou Encarregados de Educação e famílias na escola numa perspetiva cronológica, a tipologia de envolvimento parental na escola, os sistemas que influenciam o desenvolvimento da criança e ainda uma referência aos benefícios para a comunidade educativa do envolvimento parental e familiar na escola. Através dos dados obtidos, pudemos verificar que o acompanhamento dos pais ou Encarregados de Educação no Estudo Autónomo e Trabalhos de Casa e nos projetos de turma traz bastantes benefícios para todos os elementos da comunidade educativa, sendo o aluno o mais beneficiado, e influenciado primariamente pela família em articulação com a escola e comunidade. Também verificamos que os pais ou Encarregados de Educação têm necessidades de estarem informados sobre conteúdos escolares e serem conhecedores das estratégias utilizadas na sala de aulas pelo que, sem isto, apresentam dificuldades em acompanharem os seus educados em casa. A realização deste estudo visa contribuir para a compreensão das necessidades sentidas pelos pais ou Encarregados de Educação no acompanhamento do Estudo Autónomo e Trabalho de Casa e as formas de dinamizar a cooperação entre o professor da turma e a família, promovendo o sucesso e a motivação escolar. Palavras-chave: Cooperação; Envolvimento; Família; Alunos; Escola.

Serological survey for Chagas' disease in school children in the Rio de Janeiro State, Brazil

A serological survey for Chagas' disease was carried out in school children in the Rio de Janeiro State, a zone considered as non-endemic for the infection. A total of 168 schools in 20 municipalities have been visited and 13,254 blood samples were obtained. The blood eluates were screened by the indirect fluorescence test (IFT), and all positive samples were checked and confirmed in sera by the complement fixation test (CFT). AH serologically positive children were subject to a clinical scrutiny, and the houses where the children lived have been searched for triatomine bugs. Only in two municipalities, Magé and Araruama, there was a significant number of children found positive. The total number of reactive samples by IFT and CFT from 13,004 blood samples screened was 143 (1.00 per cent). No serious clinicai symptoms suggestive of Chagas' disease have been found in any of the positive children, and no triatomine bugs were discovered in the dwellings where the children lived. The overall small percentage of children with positive serology postulates that the infection is not a serious health problem in the area investigated. It is recommended, however, to carry out a more detailed study in Magé and Araruama to find the reason for the relatively high percentage of serologically positive children encountered in these two municipalities.

The Management of the Allergic Child at School: EAACI/GA2LEN Task Force on the Allergic Child at School

Allergy affects at least one-quarter of European schoolchildren, it reduces quality of life and may impair school performance; there is a risk of severe reactions and, in rare cases, death. Allergy is a multi-system disorder, and children often have several co-existing diseases, i.e. allergic rhinitis, asthma, eczema and food allergy. Severe food allergy reactions may occur for the first time at school, and overall 20% of food allergy reactions occur in schools. Up to two-thirds of schools have at least one child at risk of anaphylaxis but many are poorly prepared. A cooperative partnership between doctors, community and school nurses, school staff, parents and the child is necessary to ensure allergic children are protected. Schools and doctors should adopt a comprehensive approach to allergy training, ensuring that all staff can prevent, recognize and initiate treatment of allergic reactions.
